WASHING-MACHINE.

Specification of Letters Patent. Patented May 24, 1921.

' Application filed October 11, 1920. 'Serial No. 416,124.

To an whom it may concern:

Be it known that I, SAMUEL D. CARPEN- TER, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Washing-Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin s, forming part of this specification.-

y inventlon relates generally to washing machines and more partlcularly to that type of washing'machine in which the fabrics to be washed are placed in a clothes container which is agitated in a suitable compartment or tank.

The principal objects of my invention are, to provide a washing machine which is simple in operation and of durable construction, and which will efiiciently and quickly wash and rinse'the clothes without t'he'necessity of transferring the same to various tanks or tubs.

provide a washing machine having a movable clothes container adapted to agitate the clothesplaced therein and provided with suitable connections whereby cleansing or rinsing fluid may be circulated throughsaid container at the will of the operator.

Another object of my invention is to provide a washing machine having a plurality of compartments which are ada ted to contain various cleansing and laun ry solutions such as soap suds water, rinsin water, bluing water, and suitable connections for con necting said compartments with the washing tank containing the clothes to be washed.

A still further object of my invention is to provide a clothes container for Washing machines adapted to be actuated so as to the line 3-.-3 of Fig. 2.

on t line 4--4-o:t Fig. 3 and partially broken away to more clearly illustrate the invention.

Fig. 5 is a vertical cross section taken on the line 5-5 of Fig. 3.

Fig. 6 is a cross section taken on the line 6-6 of Fig. 4.

Fig. 7 is a fragmentary cross section of the cylinder. n

Fig. 8 is a longitudinal cross section taken on the line 8--8 of Fig. 4.

Fig. 9 is a perspective view of the end of the driving shaft.

Fig. 10 is a perspective view of the cylin der trunnion adapted to cooperatewith the driving shaft. A further object of 'my invention TS to Fig. 11 is a detail view of one of the valves utilized for controlling the connec:-

tion between the washing compartment and the soap suds and clear water tanks.

Referring by numerals .to the accompanying drawings, 10 represents the framework of thewashing machine having side walls 11 and 12 and end walls 14. and 15. The chamber within these walls. is divided by Fig. 4 is a horizontal cross section taken.

.85 means of a vertical transverse wall 16 into two compartments 17 and 18 17 is the washing tank or main compartment and is provided with bottom wall 19. auxiliary tank and can be used either as a soaking tank or bluing tank and is provided with bottom wall 20.

, The space under the washing tank is in? closed by bottom wall 21'and vertical end wall 22v to form a chamber which is divided by a' vertical longitudinal wall 24 into two smallertanks, one of which, 25, is arranged to contain clear or rinsing water, and the other is a soap suds tank 26. Under tank 18 and suitably supported on framework 10' is an electric motor 27. Pump 28-having an inlet pipe 29- and an outlet p1pe30 1s adapted to be driven by motor 27 and is con- 18 is the trolled by clutch 31. The inlet pipe 29 is rovided with branch pipes 32 and 33.

ranch pipe 32 connects pump 28 with the soap suds tank 26 and is controlled by valve 34. Branch pipe 33 connects pump 28 with clear water tank 25 and is controlled by manually operated valve 35. The outlet pipe 30 extends outwardly and upwardly of side wall 12 and terminates in the cylinder bearing 37 which is fixed to the inner side of side wall 12.

A reduction gearing 38 located in housing 39 is geared to pinion 40 of motor 27 and drives shaft 41- which extends upwardly adjacent to side wall 11 and operates wringer 42. Clutch 44 controls wringer -42 so that it can be disconnected from shaft 41. A shaft 45, also driven by gearing 38, extends upwardly and rearwardly and operates suitable cylinder reversing mechanism 46 supported on side wall 11. The reversing mechanism can be disconnected from shaft 45 and rendered inoperative by means of clutch 47. A short horizontal shaft 48 extends outwardly from the reversing mechanisni through side wall 11 into chamber 17 and its end is provided with a recess 48,

non-circularin cross section.

The washing compartment 17 is provided with a cylinder 49 having a header 50 and an end wall .51. ranged for rotation in said compartment by means of a hollow trunnion 52 which is fixed to header 50 and adapted to operate in bearing 37 on side wall 12 and by means of a trunnion 54 carried by end wall 51 and adapted to be seated in the recessed end of shaft 48. A locking plate 55 hinged to the recessed end of shaft 48 locks trunnion 54 in position on saidshaft by means of a butterfly nut 56. Cylinder 49 is made of foraminous material in order to readily drain the water.

Longitudinally disposed on the innner periphery of said cylinder are paddles or stirrers 57 which are of hollow construction and communicate-with chamber 50 in the header 50. The walls of said paddles taper I toward the axis of the cylinder and formed in theapex of each paddle are orifices 57". The end of inlet pipe 30 enters bearing 37 and terminates within the hollow trunnion 52 so that connections are established between tanks 25 and 26 and Paddles 57 by means of branch pipes 31 and 32 in pipe .29, pump 28 and outlet pipe 30 and which connections are controlled by means of manually operated valves 34 and 35.

By making hollow trunnion ,2 conical I and recessing the end ofsha ft 48, cylinder 49. can be removed from tank 17 by releasinglocking plate 55, raising trunnion 54 out of recess 48* in which it was seated, moving cylinder 49 toward side wall 11 until trun- -nion 52 is displaced from bearlng 37 when cylinder 49 can be lifted out of tank 17.

The cylinder 49 is arsuds tank and valve permits the draining of the clear Water tank. Tank 17 is provided with a drain valve 66 and tank 18 is provided with drain valve 67. i

In order to maintain the solution in the soap suds tank at the proper temperature, a suitable heating member 68 is located directly below said tank and is controlled by valve 69. I

In the operation of my improved washing machine, tank 25 is filled with clear water through valve 60 and tank 26 is filled through valve 59. The soap suds solution in tank 26 is heated by heating means 68 to the desired temperature at the same time partially heating water in tank25 by virtue of thefact that portion of the heat is imparted to Water in tank 25 through wall 24. The soiled fabrics are placed in cylinder 49 through the door 58 which is then opened while'valve 35 remains closed and valve 59 is opened and valve 60 closed.

Motor 27 is set in operation so that pump 28 is actuated whereby the heated soap suds solution is forced to circulaththrough branch pipe 31, controlling valve 34, inlet connection 29, to pump 28, thence through outlet pipe 30 into the chamber 50 in header 50 where the soap suds solution is distributed under pressure tothe hollow paddles or stirrers 59 from whichit issues in jets or streams through apertures 57 thoroughly spraying the fabrics or clothes placed ,in cylinder 49.

As the cylinder is made of foraminous material, the solution after passing through the fabrics in cylinder49 leaves the cylinder and returns through valve 59 into the ,tank 26 carrying with it the dirt and sedilocked in its closed position. Valve 34 is fabric, raise it out of the water for a short distance, and then drop it back again. This comblned action of spraying and forcibly circulating the cleansing fluid through the clothes and of agitating the same thoroughly washes and cleanses the fabrics without injury. After the fabrics have been subjected to this Spraying and agitating action for the desired length of time, pump 28 is stopped by means of clutch 31 and valve 34 is closed. Preferably the cylinder 49 is operated for a short period of'time after the circulation has ceased with the valve 59 opened in order to drive all thesoap suds solution from the fabrics by the agitating action of the cylinder and to permit the solution to return into tank 26."

In the next operation, valves 35 and 60 are opened while valve 59 is closed. Pump 28 is setin operation whereby clear water is forced to pass from tank 25 through branch pipe 32, valve 35,,and inlet pipe 29 into pump 28 and thence through pipe 3O in header 50 and orifices 57 in paddles 57 so that it is sprayed upon the washed fabrics.

The spent water is drained through the open valve 60 into tank25 to be again forced to circulate through the system by pump 28. After the wash. is thoroughly rinsed, valve 35 is closed and pump 28 is rendered inoperative. The rinsed clothes can now be placed in the tank containing bluing water;

through inlet pipes 32 and 31, tanks 25' and 26-are provided with strainers 70. Re:

movable covers 71 are provided to close open tops of tanks 17 and 18. i

By providing a plurality of tanks and connections therefor, the clothes can be washed, rinsed and bluing introduced while the same are in the cylinder, with the least amount of time-and labor. The advantages of my washing machine are readil appar ent; when the amount of time and abor, re-

' quired for transferring the wash from the wash tank into the rinsing tub and then into the bluin tank and the wringing operations 1 incidenta thereto are taken into consideration. The saving in the wear and tear of the fabrics washed by reducing the number of the wringing operations, or, if desired,

eliminating the same altogether, in itself is a valuable improvement.

A washing machine of mdy improved construction isof simple and urab e construction, can'be manufactured at lowcost, is highly efficient in operation, and performs its intended functions effectively-and without injury to the fabrics.
